I had the injectors revised 3 months ago and we installed them, the car was working fine until this time. Nowadays, I started to get the same errors again and my car shakes like a cradle, I turn the ignition off and on, it gets better for a while and then it repeats. Friends who are going through this situation, please help me. Especially when I buy diesel from different places, this situation becomes more frequent. Please help. 2.0 tdi a3 and i have a maf sencor fault code.
